Abstract

An effective amount of active/cyclodextrin complex, in the form of particles having particle sizes below about 12 microns, is incorporated into solid consumer product compositions. The complexes provide fast release of the active when they are wetted even when the amount of water available to effect release of the active is limited as in personal use compositions like drugs, foods, and cosmetics where active release is typically effected by body fluids. Preferred actives include perfumes, flavors, and pharmaceutical materials that are used by consumers.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. Solid consumer product composition comprising an effective amount of active/cyclodextrin inclusion complex prepared by the kneading method and having a particle size of less than about 5 microns wherein said active is flavor material. 
     
     
       2. The composition of claim 1 wherein said cyclodextrin is selected from the group consisting of: unsubstituted cyclodextrins containing from about six to about twelve glucose units; derivatives of said unsubstituted cyclodextrins; and mixtures thereof, and wherein said cyclodextrin is capable of forming inclusion complexes with actives. 
     
     
       3. The composition of claim 1 wherein at least a major portion of said cyclodextrin comprises cyclodextrin selected from the group consisting of alpha-cyclodextrin; beta-cyclodextrin; gamma-cyclodextrin; and mixtures thereof. 
     
     
       4. The composition of claim 1 wherein at least a major portion of said cyclodextrin is beta-cyclodextrin. 
     
     
       5. The composition of claim 1 wherein said composition is a powdered mix that is made to be mixed with water. 
     
     
       6. The composition of claim 5 wherein said mix is a drink mix. 
     
     
       7. The composition of claim 5 wherein said mix is a soup mix. 
     
     
       8. The composition of claim 5 wherein said mix is a sauce mix. 
     
     
       9. The composition of claim 1 wherein said composition is made to be applied to the surface of food. 
     
     
       10. The composition of claim 1 wherein said flavor material is spice. 
     
     
       11. The composition of claim 1 which is an instant coffee. 
     
     
       12. The composition of claim 1 which is an instant tea mix. 
     
     
       13. The composition of claim 1 which is an instant orange flavor mix. 
     
     
       14. The composition of claim 1 wherein said flavor has multiple components. 
     
     
       15. The composition of claim 14 wherein at least a major portion of said cyclodextrin is selected from the group consisting of alpha-cyclodextrin; beta-cyclodextrin; gamma-cyclodextrin; and mixtures thereof. 
     
     
       16. The composition of claim 14 wherein at least a major portion of said cyclodextrin is beta-cyclodextrin.
